IMPROVED BREAD-KNIFE.

TO ALL WHOM IT MAY CONGERN:

f Be it known that I, JOHN FRIscH, of Albany, in the county of Albany,and State of New York, have invented certain new and useful Improvementsin Bread-Knives; and dorhereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification, in which- Figure 1 represents aplan view of my bread-knife, and

Figure 2 a side elevation of the same.

The nature of this invention consists' in providing` a knife with anadjustable gauge, constructed substantially as and for the purposehereinafter set forth.

To enable others skilled in the art to make and use my invention, IYwill now proceed to describe its construct-ion and operation.

A designates a knife-blade, which is to be adapted in width to thepurpose for which it is intended. Band C represent two verticalbars,lwitl1 grooves cut on their inner sides. The bars B and Clare heldtogether by means of the horizontal metal tie E. On the inner surface ofeach of the bars B and C'is a slotted slide, g, which Vis allowed toplay vertically between the face of said bars and shoulders formed ateach end of tie E. h represents a roller, placed directly above the tieE, and pivoted in thc bars B and C, the pivots at the outer ends of saidroller being made to pass through the slides y g, so that the slidcs,`intheir descent, will not escape from the pivots. In order to keep theslides gg in position, they are furnished or cast with projections nea-rtheir lower ends. Said projections slide up and down in the grooves cutin the bars B and C. H represents another roller, pivoted in the lowerends of the slides g g, and situated immediately beneath the slotsorgrooves in said slides.' fm designates a curved spring, the upper orconvex side of which is secured, atiits centre, to the tie E. The endsof said spring rest, at the bottomvof the grooves, in the slides g g. nrepresents the shoulde'r of-the knife between the blade and handle, andis made of suiiicient thickness tn havc a mortise through it, to receivethe arm c, said arm' being placed at right angles with. the bar B, andcast solid with said bar. The arm k is made adjustable, and secured inposition by means of a thumbscrew, t.

In operating my bread-cutter, the rollers will b c adjusted to suit. thethickness of the slices required, by moving the arm 7c to the properdistance from the knife-blade, and securing it bythe thumb-screw t. Thenout the loaf downwards, and the rollers will answer as a gauge to insureuniform thickness in the slices, and also assist in expelling the slicefrom between the knife and gauge. When the knife has passed through theloaf, the spring` m, pressing on the lower roller, will canse saidroller to act as a shield to prevent the knife from damaging the tableon which the bread is placed.'

What I'claim as new, landfdesire to secure by Letters Patent, is-

1. The employment of roller II, when arranged to regulate the thicknessofa the slice, and also to yield to the pressure of the knife,substantially as and'ior the purposes described.

2. In combination witlrthe above, I claim spring m,`b:1rs B C, slides gg, and roller h, all arranged substantially in the mannerand for thepurpose set forth. A

In testimony that I claim the foregoing as rnv own, I a'lix my.signature in presence of two witnesses.

JOHN Faison.
